Multi-Database Reporting & Business Data Integration

A database integration and reporting concept for combining data from multiple systems (e.g. sales, customer records, spreadsheets, legacy databases) into one reporting-ready structure.

Overview

This project demonstrates how to bring together business data from multiple sources into a single reporting-friendly database layer. It is designed for organisations that store information across separate systems (for example spreadsheets, Access files, web forms, and operational databases) and need clearer visibility across jobs, customers, and performance.

The focus is on structured schema design, consistent field mapping, and reliable reporting outputs. The solution is suitable for internal dashboards, operational reporting, and future business automation.
